UNS K93600 Good price 36 Invar rod iron-nickel Feni alloy wire 4j36

36 Invar is a Nickel-Iron alloy with about 36% Nickel and the remainder being Iron. It is a low-expansion alloy known for its extremely low coefficient of thermal expansion (CTE), making it ideal for use in applications requiring high dimensional stability across temperature changes. Invar 36 maintains its size and shape even under significant temperature variations, making it essential in industries where precision is critical.

This alloy is widely used in the manufacturing of precision instruments, scientific apparatus, aerospace components, and high-performance machinery where temperature-induced expansion could cause inaccuracies or failure.

Key Features:

Nickel Content: 36%
Low Thermal Expansion: Approx. 1.2 × 10⁻⁶ /°C (low CTE)
High Dimensional Stability: Suitable for precise applications where size and shape need to be retained under temperature variations
Magnetic Properties: Ferromagnetic at room temperature
Excellent machinability: Can be easily formed, welded, and processed into various shapes and sizes
Corrosion Resistance: Resistant to corrosion in many environments, though it may require coatings for harsher conditions
High Strength: Provides strong mechanical properties for high-performance applications

Typical Applications:

Invar 36 is used in fields where thermal stability, precision and resistance to thermal expansion are critical, including in applications such as:

Precision alloys are metal materials with special physical properties (such as magnetic, electrical, thermal and other properties). The vast majority of precision alloys are based on ferrous metals, and only a few are based on non-ferrous metals. Usually include magnetic alloys (see magnetic materials), elastic alloys, expansion alloys, thermal bimetals, electrical alloys, hydrogen storage alloys (see hydrogen storage materials), shape memory alloys, magnetostrictive alloys (see magnetostrictive materials), etc.

Soft magnetic alloys are a class of alloys with high permeability and low coercivity in weak magnetic fields. According to the different elements that make up the alloy, it can be divided into electromagnetic pure iron (industrial pure iron), iron-silicon alloy, iron-nickel alloy, iron-aluminum alloy, iron-silicon-aluminum alloy and iron-cobalt alloy, etc.1J06,1J12,1J17,1J18,1J22,1J30,1J36,1J38,1J46,1J50,1J51,1J54,1J76,1J77,1J79,1J80,1J85,1J87

Permanent magnet alloy not only has high hardness and mechanical properties, but also has strong anti-demagnetization ability, high coercivity value (greater than 20kA/m), magnetic "hard" and other characteristics, so it is also called hard magnetic alloy.2J04,2J07,2J09,2J10,2J31,2J53,2J84,2J85Elastic alloys include high elastic alloys and constant elastic alloys. It is used to make elastic elements such as elastic sensitive elements, energy storage elements and frequency elements in precision instruments.3J01,3J21,3J53Expansion alloys(Invar Alloy) are divided into Kovar alloys, ceramic sealing alloys, low expansion alloys, and constant expansion alloys. Widely used in electronic industry, precision measuring tools, precision instruments and low temperature engineering and other fields.4J28,4J29,4J32,4J33,4J36,4J40,4J42,4J50
Precision alloys with nickel, chromium, aluminum and iron as the main components, the resistivity is about three times higher than that of manganese copper, and has a lower temperature coefficient of resistance and low thermal potential to copper, with good long-term resistance stability and resistance. Oxidation properties.
It is suitable for making precision resistance elements in various measuring instruments and meters, making precision micro-resistance elements and strain gauges.6J10,6J15,6J20,6J22,6J23,6J24
